Concrete Repair

Concrete Repair Excellence from Flexcrete

At Flexcrete we manufacture and supply a comprehensive range of concrete repair systems, perfectly suited to both new build and refurbishment construction projects. We have a vast range of specialist products that are designed to solve complex structural problems and reinstate structural integrity whilst causing the minimum of disruption during application.

Our concrete repair & protection products include structural repair mortars which can be applied up to 100mm in a single application, fast setting mortars designed for rapid reinstatement of heavily trafficked areas and cementitious coatings designed to reinstate low concrete cover; a simple 2mm application provides the equivalent of 100mm good quality concrete cover and offers low permeability to water, even at 10 bar positive and negative pressure. For a decorative finish, we offer a range of Monodex weatherproof anti-carbonationcoatings which provide the ultimate protection against the ingress of carbon dioxide, oxygen and water and are available in smooth, textured and clear variants.

As our concrete repair and protection products have environmentally friendly, water-based, low hazard formulations, they are ultra-low odour and release no hazardous solvents during application. Daily routines can continue as normal and there is absolutely no disruption to other trades during new construction or refurbishment work. Our products are CE marked and comply with the demands of EN 1504, the pan European standard for concrete repair, so they can be relied upon with absolute confidence. They have an outstanding track record of use on buildings and commercial construction all around the world.

Solutions for Concrete Repair & Protection - Commercial Buildings

At Flexcrete, we have extensive expertise in the concrete repair and protection of all types of buildings and structures. Download this information sheet to find out more about the benefits that our materials offer.

The Need for Periodic Maintenance

Today, reinforced concrete is one of the most common building materials in the world. However, when subjected to the elements and environmental attack, even the most well-designed structures, constructed using the best quality concrete, need repair and protection.

Factors such as carbonation, water penetration, chemical attack, freeze/thaw cycling and chloride attack can all lead to significant deterioration of precast and in-situ concrete. Steel reinforcement can quickly corrode and compromise structural integrity. It is therefore essential to carry out periodic maintenance in order to guarantee the original design life of buildings and, above all, keep the people and contents within them safe.

The Solution

Missing or removed concrete is then reinstated. Where a high build structural repair mortar is required, Monomix is the best choice.

For general purpose repairs, Monolite, a low density mortar can be used. Monolite can be applied in thicknesses up to 100mm in a single layer.

Afterwards, Monolevel FC may be applied to all surfaces using a bag rubbing technique to achieve a fair-faced finish, prior to the application of a decorative anti-carbonation coating such as Monodex Smooth.

The Problem

Extensive corrosion caused by chlorides, resulting in loss of steel section and large areas of spalling. The source can be chlorides which are cast-in, or those which ingress from external sources such as de-icing salts.

The Solution

Monomix can be hand applied to re-profile small areas of damage and a special grade, Monomix WS, is available for application by wet process in larger areas.

Cemprotec MCI® 2020 will diffuse through the concrete structure to form a protective layer on the reinforcement to protect it from corrosion in chloride contaminated structures.

The Problem

Carbonation

To give proven protection against carbonation and so extend the design life of a reinforced concrete structure. Such a barrier prevents further corrosion of steel reinforcement and subsequent spalling of the surrounding concrete.

The Solution

Following repair, the complete structure is treated with Monodex Smooth, a coating with outstanding anti-carbonation properties. This highly aesthetic coating also has excellent weathering and UV resistance and a serviceable life of at least 15 years.

Where aesthetics are of lesser importance, two 1mm coats of Cementitious Coating 851 will also provide long term protection for the design life of the structure.

The Problem

Low Concrete Cover

Low cover to reinforcement provides insufficient corrosion protection to the reinforcement. Reduced design life and durability is the result.

Concrete Repair Products

Flexcrete offers an extensive range of engineering quality, waterproof concrete repair mortars for both structural and cosmetic repairs. Primers are not required and packs can be split and simply mixed with water. Our range includes Monomix mortars, easily applied up to 80mm in a single application, Fastfill which is designed to allow rapid return to service especially in heavily trafficked areas and our lightweight mortar Monolite.

For a decorative, protective finish our Monodex anti-carbonation coatings are water-based, environmentally friendly and available in a wide range of attractive colours. With a design life of 10-15 years before first maintenance, Monodex coatings provide years of protection against general weathering, carbonation and water ingress, yet allow damp substrates to breathe without blistering or delaminating. Our clear anti-carbonation coating, Monodex Clear, also demonstrates exceptional resistance to carbon dioxide diffusion.

Flexcrete’s versatile admixture products are specifically designed to enhance cementitious mixes in order to achieve improved mechanical characteristics with excellent resistance to oil, water and abrasion.

Flexcrete offers various anti-corrosion measures which can extend the lifespan of infrastructure and buildings. For example, our surface-applied corrosion inhibitors are specially formulated to migrate through concrete on existing structures to seek out and help protect the steel reinforcement.

The Latest Cementitious Technology

Technical innovation is key at Flexcrete and our investment in Research and Development means that we can offer the most technologically advanced and innovative repair and protection materials. Our concrete repair products incorporate a unique blend of polymers, microsilica and fibres, and are simply installed using spray-applied, trowel-applied and pourable techniques.

Flexcrete’s concrete repair products are used to solve complex structural problems and are widely respected by designers, engineers and contractors alike. They offer the ultimate protection against chemicals, chloride ions, carbonation, water penetration and other aggressive forms of attack and have a long track record of success in some of the world’s most hostile environments.
